Ting-Wei "Willy" Sun, a former contractor whom prosecutors describe as a "fixer," pleaded guilty in a Manhattan federal court on Thursday to four counts, including conspiracy to violate US export controls, as part of a deal with prosecutors, Bloomberg reported. Sun will be sentenced in September 2027.
What the guilty plea covers
Sun admitted to helping send servers powered by Nvidia chips to a company in Southeast Asia, which then diverted them to customers in China, according to prosecutors. The chips in those servers are barred from sale to China under US export rules. In March, prosecutors charged Sun and two others with conspiring to divert about $2.5bn of US AI technology, Reuters reported. His lawyer declined to comment to Bloomberg.
The exposure attached to this charge is specific. The US Department of Justice says that conspiring to violate the Export Controls Reform Act carries a maximum term of imprisonment of 20 years. The maximum is set by Congress, and the actual sentence is decided by a judge.
How prosecutors say the scheme worked
The indictment says the group tried to fool auditors. The dummy units were presented for inspection at the locations where the servers were supposedly being stored, while the real hardware moved on toward China.
The volume grew quickly. The US Department of Justice says that between late April 2025 and mid-May 2025 alone, at least approximately $510 million worth of the U.S. Manufacturer’s servers, assembled in the United States, were diverted to China in violation of U.S. export control laws as part of the defendants’ scheme. The Justice Department also noted that neither the defendants nor the manufacturer held a license from the US Department of Commerce to export those servers to China.
Where the other defendants stand
Super Micro co-founder Yih-Shyan "Wally" Liaw was charged in March and has pleaded not guilty. He has left the company’s board. A third man, former Taiwan sales manager Ruei-Tsang "Steven" Chang, has not appeared in court.
Super Micro Computer is not a defendant. The company said in August that its current senior leaders did not know about the scheme and that it is working with investigators.
A widening enforcement pattern
The plea arrives as the Justice Department presses more cases over advanced AI hardware. Last week, US prosecutors charged a California man with sending $300mn of AI servers to China.
What this means for you
Keeping clear vendor records, verifying hardware origins, and matching asset tags to invoices are sensible habits for any IT operation. These steps use only what the case and the Justice Department have laid out.
- Record the serial number and asset tag for every server and workstation, and reconcile them against the purchase invoice.
- Buy from authorized vendors or resellers and keep documentation that shows where the hardware came from.
- If you ever ship, resell, or move hardware across borders, confirm who the actual end user is.
- Check whether any gear you handle contains export-controlled components, and whether a Commerce Department license applies before it leaves the country. The Justice Department noted that no such license existed in this case.
- Brief whoever handles procurement so these checks are part of ordering, not an afterthought.
